After one hour, the plane is 225 miles from its destination
The TV is 45 inches tall.
Step-by-step explanation:
The diagonal length of television = 53 inches
Width of TV = 28 inches
As TV is in rectangular or square shape, a diagonal will form a right triangle
Where,
Diagonal = hypotenuse = c = 53 inches
Width = base = b = 28 inches
Length = perpendicular = a
we will use pythagorean theorem to find the length.

Taking square root on both sides

The TV is 45 inches tall.

In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:
sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
